  • In this paper, we perform a simulation study of genetic model-free age-of-onset methods in linkage tests which has been proposed by Zhu et al. (1997). They performe. Haseman-Elston regression on a set of bipolar pedigree data using each of three dependent variables: a binary trait indicating disease concordance or discordance, a binary trait adjusted for age-of-onset, and the residuals from a survival analysis. We compare the powers of the proposed test statistics for various situations. Simulations that we have carried out show that the gains in power are observed when the residuals from a survival analysis are used in linkage tests.

  • Determination of sex origin of cattle meat by fast and reliable molecular methods is an important measure to ensure correct allocation of export refunds particularly in European countries and also female cattle (cow) slaughter is legally banned in India because of religious beliefs. Based on the DEAD box protein gene located on the X and Y chromosomes, 2 pair of primers were designed and the system of PCR was optimized. Upon PCR amplification, male tissue showed 2 bands, while female tissue resulted in only one band. The accuracy and specificity of the primers was assessed using DNA template extracted from cattle meat of known sex. The protocol was subjected to a blind test and showed 100% concordance, proving its accuracy and reliability.

  • Recently natural disasters such as the frequency and intensity of drought have been increasing as a result of climate change. This study suggests a drought index, WADI (Water Availability Drought Index), that considers water availability using 6 components (water intake, groundwater level, agricultural reservoir water level, dam inflow, streamflow, and precipitation) using the Z score and data monitoring on a nationwide level. SPI (Standardized Precipitation Index) was applied in coastal area. For the severe droughts of 2001 spring and 2008 autumn, the index was evaluated by comparison with reported damage areas. suggested to combine The spatial concordance rate of WADI in 2001 and 2008 for estimation of the degree of drought severity was 50 % and 24 % compared to the actual recorded data respectively.

  • The purpose of this study was to identify the accuracy rates(hit ratio) which mean the degree of concordance between pain rating scale differences over time & subjective comparisons. Subjective comparisons mean the responses to the question “how does the pain you are now experiencing compare with the one at the time of the assessment yesterday\ulcorner” Answers to this question were translated into ‘greater’, ‘same’, or ‘less’. KPRS(Korean Pain Rating Scale) was developed through 4 consecutive studies to assess pain extensively & accurately by Lee etc. VAS(Visual Analogue Scale) was reported as valid & veliable measure for the intensity of pain by many researchers. Thirty hospitalized patients with complaints of Headache were partispated in this study during the period from May 1 to July 31, 1987. In conclusion, the accuracy rates of KPRS and VAS were 60%, 67%, respectively.

  • This study evaluated attachment representation of school aged children, its relation to classification of family drawings, and their association with children's perceptions about families. The attachment representation of 43 children 6-9 years of age was evaluated by the Manchester Attachment Story Task (Green, Stanley, & Goldwyn, 2003) children's family drawings were classified by Fury's Family Drawing Scales (1996). Results showed that 12 children (28%) were avoidant, 23 (54%) secure, 4 (9%) resistant, and 4 (9%) were disorganized. Classification of childhood attachment representation showed a high concordance rate (86%) with family drawings. Securely Attached children showed positive perceptions such as family pride/happiness and vitality/creativity while Insecure children showed negative perceptions like emotional distance, tension and bizarreness.

  • the two Korean causal conjunctive suffixes, -nula(ko) and -nun palamey, based on corpus linguistic analysis. Many of the linguistic accounts available, both in pedagogical reference and in the literature on linguistics, provide incomplete analyses of these suffixes, based on fabricated linguistic data. Using naturally occurring, real linguistic data, this paper examines the syntactic and semantic structures of the two causal suffixes through a consideration of three areas of corpus linguistic analysis: token frequencies, collocations, and semantic prosody. An analysis based on concordance data reveals that the two causal connectives, -nula(ko) and -nun palamey, have more differences than similarities in terms of syntactic and semantic constraints. The idiosyncratic structures of the two suffixes are discussed in terms of same subject condition, verb selection, same agent condition, synchronicity condition, and negative semantic prosody.

  • To assess the awareness of cervical cancer among couples, data were collected from two urban slums community in Mumbai. A total of 1958 married women aged from 18 to 49 and their husbands were selected using simple random sampling. Women (37.7%) were significantly more aware of cervical cancer than husbands (8.7%). A slight agreement (kappa statistics=0.16) was observed between husbands and wives on awareness of cervical cancer. Significantly higher percentages of wives were aware of pap smear test than husbands. Overall, awareness of cervical cancer and pap smear test among couples is low. There is need to educate and motivate both of them to participate in cervical cancer screening program.

  • This paper addressed various issues related to the objectivity of student assessment in medical education. The objectivity of assessment was related to all the steps of test development, administration, and results reporting in terms of reliability and validity. Specifically, the objectivity of item formats, representativeness of test content, standardization of test administration, consistency of scoring procedures, and appropriateness of reporting test results were discussed by comparing performance assessment with traditional paper-and-pencil tests. The conclusions were derived from current measurement theories such as standards-based assessment, evidencebased design, and outcome-based assessment. Further, based on Shepard's propositions (2006), the objectivity of student assessment could be achieved by improving the concordance between educational objectives and assessment components such as item types, test contents, and test administration, scoring, and reporting.

  • As a step preliminary to the factor-analysis of a child-rearing attitude scale under construction, its preliminary form containing a total of 368 self-answered questions was administerd to 88 married women with one or more children in the grade school age. all graduates of colleges and in possession of a home telephone and a house, twice from one week apart. The test-retest correlation coefficients, calculated for each test item based on the subject's choice among the three response alternatives on two test ocasions, ranged from .80 to .10. The cut-off point of r=.41 or lower led to the elimination of 48 items. As a point of incidental interest, the rate of response concordance. The namber of subjects giving the same categroy response on two occasions was calculated for each item and it was correlated with its test. retest correlation coefficient. The two different indices of item test-retest reliability were found not related to each other. Empirical evidence, as well as rational justifications, was presented to show that the correlation coefficient is the better of the tow indices of item test-retest reliability.
